This is a set of seven large glass slides depicting images of the moon. Each 12cm x 16.5cm slide appears to be a copy of a page of a photographic atlas called “Photographie Lunaire” by Maurice Loewy and Pierre Puiseux (1910). Some of the slides have a red and white sticker in one corner.
These slides are contained in a cardboard box that originally held unexposed slides. This has a warning label on the front.

These slides were possibly used for demonstration or teaching.
Fair: The slides themselves are in good condition, although they are all slightly chipped around the edge, and in places the film is beginning to peel off the glass. The stickers stuck to the glass plates are very worn and dirty and rendered illegible. The cardboard box has collapsed; all the corners are worn and torn, and the surface of the box very dirty.
Slides: Unknown; Images: Maurice Loewy & Pierre Puiseux; Exposures: Unknown

It is unknown when these slides were produced, or why. They may be associated with teaching at the Department of Astronomy, or with work done at the David Dunlap Observatory. If the latter, they were likely moved from the David Dunlap Observatory in Richmond Hill in 2008, upon the sale of the observatory. It was stored at the Department of Astronomy and Astrophysics until 2017, when it was moved to a new storage location in McLennan Physical Laboratories.
The Metropolitan Museum holds a photogravure by Loewy & Puiseux, <a href=https://www.metmuseum.org/art/collection/search/265630>and provides some information</a> about their work [24/01/18].
